ABSTRACT
This chapter describes the components of Digital Video Broadcasting–Handheld (DVB-H) corresponding to its physical layer, as well as its service information features. It explores the link layer of DVB-H MultiProtocol Encapsulation (MPE), on which the data transmission is based at this level, and the main technological innovations of DVB-H: time slicing and MPE–Forward Error Correction (MPE-FEC). In addition to video and audio data, an Motion Picture Experts Group (MPEG)-2 transport stream also needs to carry so-called service information. MPE has been introduced by the DVB Project for transporting the network packets from various protocols over DVB broadcast channels, that is, MPEG-2 transport streams at the physical layer level. MPE-FEC stands for Multi-Protocol Encapsulation–Forward Error Correction. MPE-FEC is an optional component of DVB-H at the transmitter level as well as at the receiver level. DVB IP datacast has been defined within the framework of DVB-H and of existing cell phone networks.
